14:10 SHADOW REGISTER
SELECTOR
RW Shadow Register Selector 11011
9 USE SERDES MODE
COUNTERS
RW 1 = use registers 12-14h for SerDes data
0 = normal operation
0
8AUTONEG FAST
TIMERS
RW 1 = speed up link_timer for test vectors
(1.6 us SGMII; 9.84 us IEEE)
0 = normal operation
0
7 JAM FALSE CARRIER
MODE
RW 1 = Transmit packet on SerDes pins with txen,
txer, txd=55h for duration of false carrier
received on copper pins in SGMII/GBIC half-
duplex mode.
0 = ignore false carriers in SGMII/GBIC mode
1
6 DISABLE CARRIER
EXTEND
RW 1 = force rxer, rxd to zeros in TRR+extend state
(pcs receive state)
0 = normal operation
0
5 DISABLE TRRR RW 1 = bypass extend_by_1 state (pcs transmit
state)
0 = normal operation
0
4 DISABLE REMOTE
FAULT SENSING
RW 1 = disable automatic remote fault sensing of
autoneg resolution errors and offline errors.
(offline errors occur in GBIC mode when the
copper link is down)
0 = normal operation
0
3 AUTONEG ERROR
TIMER ENABLE
RW 1 = enable autoneg error timer (error state
entered when error timer expires in
ability_detect, acknowledge_detect, or
idle_detect state)
0 = normal operation
0
2 COMMA DETECT
ENABLE
RW 1 = enable comma detection
0 = disable comma detection
